WS2 - Analog optical processing: back in town for neuromorphic applications?


Photonics promise of enabling non-von Neumann computing is particularly suited for neuromorphic applications, which require low latency, high bandwidth, and low energy consumption.

However, to realize practical analog optical processors further progress is needed in materials, devices, hardware architectures, fabrication and packaging, simulation software as well as calibration and control tools, and interfacing with end users.

The workshop will be an ideal venue to discuss the latest advancements and the open challenges in the field of optical processing applied to neuromorphic computing, with a particular attention to integrated photonic implementations.

WS4 - Quantum Communications and Networks Workshop

Workshop organizers:

Luis Velasco (Universitat Politècnica de Catalunya, Spain), Sandeep Singh (Indian Institute of Technology Roorkee, India), Roberto Proietti (Politecnico di Torino, Italy)


Despite many challenges in quantum computing, developments in quantum devices, quantum key distribution (QKD), quantum cryptography, entanglement distribution, quantum repeaters and teleportation open up new near- and long-term research areas in quantum optical devices, communications protocols and future quantum internet.
This workshop will provide broad overviews of QKD systems, emerging technologies, and protocols (beyond BB84), and key emerging research areas, such as quantum cryptography and security technologies. Furthermore, it will include a discussion on quantum applications beyond QKD, quantum internet architecture and protocols, network architectures for entanglement distribution and teleportation, and quantum network deployment challenges.
